Using VMware Cloud DR with VMware Cloud on AWS, you can deploy a Recovery SDDC in a recovery region and configure it as a recovery site.

In addition to deploying a new Recovery SDDC, you can also add an existing SDDC for recovery. For more information, see Add an Existing SDDC. Once you deploy a Recovery SDDC in a recovery region, it cannot be used in another recovery region.
Note: VMware Cloud DR Recovery SDDCs are bound by VMware Cloud on AWS configuration limits. For example, if you want to know the currently supported maximum number of hosts per cluster, the maximum number of SDDCs per region, or the maximum number of SDDCs per Organization, and more, see VMware Confguration Maximums.
Note: VMware Cloud DR does not currently support stretched clusters for Recovery SDDCs.
There are two types of new Recovery SDDC deployments: single-host or multi-host.
Recovery SDDC Deployment Type Description
Single-host
A single-host SDDC is designed for testing purposes and can be deployed for the following reasons:
  • A single-host Recovery SDDC can be used for building and testing your DR plans, after which you can delete the Recovery SDDC to reduce costs. A single host SDDC does not provide any data protection, does not offer production level Service Level Agreements (SLAs), and are automatically torn down in 30 days. A single-host deployment should only be used for testing purposes and is not intended for production use.
  • A single-host SDDC can also be deployed on-demand, where you deploy the SDDC after a disaster event or for DR testing.
  • You can only scale up single i3 host SDDCs. You cannot scale up a single i3en host SDDC.
Multi-Host
A multi-host SDDC deployment provides two or more hosts and can be deployed for the following reasons:
  • A two-host (i3 and i3en) Recovery SDDC provides a lower cost way to start using VMware Cloud DR for DR planning, testing, and recovery.
  • A three-host "pilot light" Recovery SDDC deployment can reduce recovery time by having a readily usable Recovery SDDC.
  • If you are not using a VMware Cloud on AWS Pilot Light, you can select an 'on-demand' deployment, where you deploy a Recovery SDDCs with one or more hosts after a disaster is already in progress or has occurred.

You can remove hosts from the Recovery SDDC as long as the number of hosts in your SDDC cluster remains above the 2-host minimum. You cannot scale down a 2-host Recovery SDDC. Ensure that you have sufficient capacity in your cluster to hold the workload VMs that will be evacuated from the hosts that you remove.

You must use the VMware Cloud on AWS UI in order to scale down an SDDC.
